* brig-builtins.def: Added a builtin for class_f64.
* builtin-types.def: Added a builtin type needed by class_f64.
* brigfrontend/brig-code-entry-handler.cc
(brig_code_entry_handler::build_address_operand): Fix a bug
with reg+offset addressing on 32b segments. In large mode,
the offset is treated as 32bits unless it's global, readonly or
kernarg address space.
* rt/workitems.c: Removed a leftover comment.
* rt/arithmetic.c (__hsail_class_f32, __hsail_class_f64): Fix the
check for signaling/non-signalling NaN. Add class_f64 default
implementation.
